Be it known that l, NAzAnnNn Momona i subjei" .of the King of Italy, residing at Chicago,'countyof (look, and State of llli-y nois, have invented certain new and useful Improvements in a Carving or Reproducing Machine, of which the following is a description. y My invention belongsto that general class of devices known as a carving or reproducing machine which will reproduce a piece of cut, carved or engraved work from' a piece of sample worlr or pattern', and produce the new work in the desired size and an exact copy of the original work or pattern. The invention-has among its objects the production of a machine ofthe kind described which is simple, convenient, compact, durable, reliable,I adjustable, eflicient and satisfactory foruse wherever found applicable. lt has particularly as an object the production of a machine by means of which sim ple or intricate patterns may be reproduced and 'the machiney operated byl one who is not a skilled mechanic to reproduce the desired pattern in a perfect and artistic manner.. The original pattern or work maybe made by a lskilled carver, engraver or mechanic, and with this as a pattern the unskilled mechanic can duplicate or reproduce it in the desired relative'size and vin a minimum of time. Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosures herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims. l

In the drawings, wherein like reference characters indicate like `or corresponding parts, y

Figure l isa view in elevation of the preferred form of my machine;

` Figure 2 is a top elevation of the saine;

. Figure G is asectional yViewy taken substanf ktion of the'machine on a diferenttype of work from that illustrated in Figure l.

lt may be mentioned that my machineis particularly intended as a reproducing machine, and is, as it is generally kno-Wma substanl carving machine, thecaiving, however, be-

ing` d one by a rotary drill. In using the machine a pattern P is prov'idedthis being generallyl made by hand by a skilled me` chanic, although the manner of constructing` the pattern'is iinmaterialin so far as the present invention is concerned.

Referring to they drawings, I provide an adjustable-frame which, in `the construction shown, consists of side bars land 2, prefer-r ably7 connected at the ends by tie oi end members 3, the whole frame being adjustably supported'onan arme or itsrequivalent, which maybe inountedaspat upon a suitable bench, box vor other support for the same. The frame and arm 4 may be of the desired material, size. shape' and construc tion, the size ordinarily depending upon the.

lrind of work which the particular machine is designed. The machine maybe constructed in sizes from a machinel of a' foot or even less. to the desired :numberof feet in. length. Mounted upon the frame is a head 6 which carries. in the construction 1 shown, a ii'iotorf or lthe equivalent'source of power arranged to 1drive shaft 8 (see Fig, 6), which is arranged totransinit power to a drivel shaft as will be hereinafter de,-k

scribed. In the vconstruction shown. the head k6 lis mounted on a head part 9,y the parts being secured in place' byplate l0 and suitable securing means not shown in detail,

such as'screws or bolts.

flrdjustablycarriedby the frame on each i side of the head 6 are adjustable or slidablev slidable heads 14 and 15.

movable post members 16 and 17 are connected through members 22 with the arms 18 and 19 respectively. The arms 18 and 19 are pivotally supported on the head 6 at 20, and are provided with intermeshing gear segments 21 so that the arms will move together, thereby operatively connecting parts 16 and 17 so that vertical movement of one, for example part 16, will be transmitted to move part 17. As shown (see Fig. 4), the brackets or parts 22 are each provided with a stud 23 which pivotally connects the same with the posts 16 and 17, permitting the ad- Ajustment of the parts, bars 18 and 19 being arranged to slide in the brackets 2 2, as will be hereinafter described. Each of the posts 16 and 17 carries a head and other mechanism, and in view of the fact that the heads are similar, a desrription of one will suffice for both, the same bearing similar' reference characters. Referring particularly to Figures 1, 7 and 8, the posts 16 and 17 are formed with forked ends 26 each of which adjustably, or pivotally in the Construction shown, carries a head member 27, the head being pivotally supported in the arms 26 of the fork by the shaft 29, and extending part 33 on the head. The head carries a depending frame 28 which is adjustably, as shown pivotally, secured to the head and supported thereby by the studs or shaft Aportions 31 and 32. The frame portion 28 carries a shaft 35 provided with a chuck 36, which carries a tool or tracer 37 on one head and a drill 37 on the other, which may be secured in place by a thumb screw 38 or equivalent means for the purpose. It will be noted from the preceding description that the members 27 and 28 at the lower ends of the posts 16 and 17 form substantially universal tool carrying heads, as they may be termed, one of which is arranged to carry the tracer, and the other the cutting tool.

, is most clearly shown in .Figures 3 and 6,' the `head 6 and frame end members 3 carryia rotatable shaft 39 which extends through the head parts 43 carried by the Shaft 39 is provided with a spiral gear 40 or the equivalent arranged to intermesh with the driving gear 41 on the driving shaft 8. Arranged in the head 43, there being one on each of the movable head parts 14 and 15, is a drive gear 45, which meshes with the gear 46 on a shaft 47 which extends down to the head on the lower ends of each of thel posts 16 and 17, `and is operatively connected with the carving tool or tracer. It may be mentioned that the gears and 46 are splined to the shafts 39 and 47 so that the head may be moved on the frame and the shaft 47 Pf m) gear 49 on the shaft 29, which shaft is arranged to drive gear 50, which in turn drives a gear 51 mounted on shaft 32, and this drives gear 52. Shaft 35 is driven from the gear 52 through the bevel gear 53, shaft 54 and gears 55 and 56.

Each of the heads or head parts 43 are connected by rods or shafts 58 and 59, which extend from endk to end of the machine and are suitably supported by the head part 6 and frame end members 3. Each head carries depending shafts 60 and 61, which are operatively connected with the head 27 so that movement of one head in any direction will be transmitted to the head on the other post and move it, or control its movements.

nasmuch as the 'iechanisms are substantially similar, a description of one will suffice for both. Referring particularly to Figures 3 and 4, shafts 58 and 59 are provided with gears 62 which mesh with gears 63 on the shafts 60 and 61. These various gears are splined on the shafts so as to permit adjustinent of the parts. The shafts 60 and 61 extend down to the heads 26. Referring to Figure 7 shaft 60 is provided with a gear 66 at its lower end, which is arranged to interengage or mesh with the gear 67 formed on or secured to the extending end of part 33 of the head. The shaft 6l is provided with a gear 68 arranged to intermesh with the gear 69, formed o'n or provided at the end of shaft 30. Shaft 3() carries a gear 70 which meshes with the gear 71 on shaft 31, shaft 31 being so secured to the frame part 28 that movement of the frame part or shaft, as the case may be, will move the other part The heads 14 and 15 are so connected that sliding movement of one head will be transmitted to the other, the connecting means shown being so arranged that the same may be adjusted to give different results. lieferring to Figure 1, well as Figure 2. .l have provided threaded rods 74, 75 and 76. These are adjustably connected together at 77-77 so as to substantially provide universal joints. Rod 75 is pivotally carried by a bracket 78 on the head 9 (see Figure 6), while rods 74 and 76 are pivoted to the heads 14 and 15 by internally threaded brackets ,79. lt will be noted by referring to Figure 1 that two of the rods, for example rods 74 and 7 5, are oppositcly threaded. @ne of the rods, as shown rod 7'4, may be inovided with a wrench 80 so that adjustment may be varied as desired by rotat ing the rods will be hereinafter described. l have shown an adjustable counterweight 82 arranged on the bar 19, the same, however, being serurcd to the adjacent bracket 82 by means of a tie bar .83, it being understood that any equivalent construction may be employed. ln Figures 1 and 2, I have shown a supporting bar or member 85 which may be of the desired size and shape for Meeres e e slidably supporting or steadying one end` rmitted from vthe head 26 through part ,33, gear 67 ,'gear 6 6, sha-ft 60, gears'62 and 63, to the4 similar mechanism on the head1-, f and down -to the tool 37. The tool will,

The supports shown may lbe arranged to not only prevent the sagging of one end but also pre- -ventits raising off otxthe support.

The operation k*of the device may be briefly described as "follows: Assuming that the` parts are set up and adjusted as Vshown in the drawings. Referring to Figurel, P

represents a pattern to be reproduced, and

lvV a block which is Ito be finishedand be a reproduction of the pattern P. The adp justment is such that the relative sizes ofy y Y, j thek pattern P and work W will be as de` sired. The tracer 37 is brought in contact with the pattermand the Ydrill 37- on ythe column or post y17 is brought in contact with the blocker work'lV.' Obviously, shaft 8k being driven will,V through the shafts 39 ande and intermediate gears described, drive the tracer 37 on, the column 16, and drill 37 on Athe column 17. The operator moves the tracer 37' over the pattern', bringing the same to every point thereon. As 'he does so, the vertical movement of the tracer will be transmitted through therod 16,;bar

18, bar 1'9, post. 17, ete., tov the ldrill 37v sol that as .the tracer is raised or lowered, the

drill or carving tool will be likewise raised" `or yilowered.` Movement of1 the tracer'from right to lett kor viceversa will, through the intermediate mechanism,` .as for example post 16, move-the head 14 ongthelt'rame, and.; its-movement will be transmitted to the fhead'15` through thek bars "or shafts, 174:, 7 51 andv 76 which move, the head y15, which will, through the intermediate mechanism "move the-:carving'toolor drill in the opposite dt rection. The frame bars 1 2 and parts 3,

"constituting vthe -frame, may be `pivoted onl i r.Ehe tracer and tool 'have substantially a universal movement at vthe bottom; of the columns or pos-ts 16 and 17 as the head27 mayfpivottreferring to Fig. 12), permitting the `toolsrto be swung yforward or backward while the pivotal connections at 31 yand 32 will permit the frame' 28 to be vswung las' indicated by the dotted lines in Figure 1. Obviously, any intermediateposition ofthe drill andtracer maybe reached. Movement ot the tracer 37 will, therefore, be transmitted through the frame 28,`shaft`31, gears and 71, shaft 30, gears 69 and '68,*shaft 61, gear 63, gear'62, to shaft 59, andjthis through'the s imilarftrain of gears and'conneetingmechanism atfthe opposite side' willy move `the drill or carving tooly carriedby the lpost '17. Likewise, movement ofthe J' lhead 27 :onthe post :16 as'. the marker' is moving-forward' or backward, will be trans-1Av therefore," be governed in its movements by j l y be. lt will be obviousthat itis immaterialY as to which post carries the tracer and which carries the tool, vas the `general prinvk y .ciple will be the same, the sizes fbeing'varied,

however, one side of the machine being controlled Yby ythe other.` I have indicated in f the dotted lines'y in `Figure l howmovement lso of one head is .transmitted by means of rods adjustment of the parts, one shaft, .as for example Ashaft 74,v is turned. The threaded `r`711, and 76`to the oppositehead. ltwill be obvious'that itit is desired to vary4 the engagement ofthe `bracket79tliereon will vary the .distance between the `bracket and the joint 77. y'lotating the shaft, however,

will causeal Vrotation of shaft 75 which has" 1 f.

a threaded engagement-with bracket`78^and the shaft being oppositely threaded, the distanceb'etween the said coupling 77 and the` bracket 78 will vbe varied.y However, rota-V- tion ot' shaft 75 will affect the 'adjustment ofbracket 79 andshaft 6, thereby varyingV .the distance kof head 15v from the renter head 6.y

l 'have shown the counterbalance '82 iter the `mechanism adjacent lthe-reto, ythe same "servingto balance thefpars at :the opposite side 'of hea'd6 which, by reason of: being` a greater distance 'romxthe yheadp, eerta greater leverage. The counterbalance *preferably connected to thebracket '22 or vtheeojuivalent so that as ithe balancevor advlt will be noted that by making-the mawhich would bepracticallyimpossible it the vltracerand tool hadlonly a vertical and slidable movement.
